[0036] In actual application, the plate is placed on the plate conveying device 1, the rotating driving mechanism 11 of the plate conveying device 1 drives all the plate conveying rollers 10 to rotate, the rotating plate conveying rollers 10 convey the plate towards the film tearing device 2, when the plate moves between the two groups of center positioning assemblies 14 and all the plate sensors 15 sense the plate, the center positioning driving mechanism 12 drives the two groups of center positioning assemblies 14 to approach each other, so that the center positioning pieces 16 on the two groups of center positioning assemblies 14 center the plate, when the centering of the plate is completed, the width measurer 13 measures the distance between the center positioning pieces 16 on the two groups of center positioning assemblies 14, so as to measure the width of the plate, and the width measurement result is fed back to the upper film material integrity detection mechanism 7 and the lower film material integrity detection mechanism 8, with the rotation of all the plate conveying rollers, the plate is conveyed to the film tearing device 2, in the process that the plate passes through the film tearing device 2, the film tearing device 2 tears the film of the plate, so that the upper film material and the lower film material are rubbed and separated from the plate, the upper film material after rubbing and separation is clamped by the upper film clamping device 5 and pulled upwards, so as to tear the upper film material from the plate, the lower film material after rubbing and separation is clamped by the lower film clamping device 6 and pulled downwards, so as to tear the lower film material from the plate, and the plate after film tearing is conveyed to the plate output roller group 23, the plate output roller group 23 then conveys the plate to the plate output mechanism 3, in the process that the upper film clamping device 5 pulls the upper film material upwards and the lower film clamping device 6 pulls the lower film material downwards, the upper film material integrity detection mechanism 7 and the lower film material integrity detection mechanism 8 detect the integrity of the torn upper film material and lower film material according to the width of the plate measured by the width measurer 13, when the integrity of the detected upper film material and lower film material is qualified, it is determined that the upper film material and the lower film material are completely torn from the plate, and the qualified plate is output by the plate output mechanism 3, when the integrity of the upper film material or the lower film material is unqualified (part of the film material remains on the plate), it is determined that the upper film material or / and the lower film material is not completely torn from the plate, and the unqualified plate on the plate output mechanism 3 is temporarily stored by the temporary plate storage mechanism 4, so as to rework the plate with residual film material.

[0037] The present application measures the width of the plate when centering the plate, the upper film material integrity detection mechanism 7 and the lower film material integrity detection mechanism 8 detect the integrity of the torn upper film material and lower film material according to the width measurement result of the plate, which improves the accuracy and precision of the integrity detection of the film material (upper film material and lower film material), and is beneficial to accurately sorting the plate with qualified film tearing from the plate with unqualified film tearing.

[0038] In the embodiment, the upper film material integrity detection mechanism 7 comprises a plurality of upper film material fixed sensors arranged in a straight line on the upper side of the film tearing device 2 along the axial direction of the plate feeding roller 10, and the lower film material integrity detection mechanism 8 comprises a plurality of lower film material fixed sensors arranged in a straight line on the lower side of the film tearing device 2 along the axial direction of the plate feeding roller 10. The upper film material fixed sensors and the lower film material fixed sensors are electrically connected with the width measurer 13. According to the width of the plate material, a selected number of upper film material fixed sensors and a selected number of lower film material fixed sensors are used to detect the integrity of the upper film material and the lower film material of the stripped plate respectively. When the selected number of upper film material fixed sensors can all detect the torn upper film material and the selected number of lower film material fixed sensors can all detect the torn lower film material, it is proved that the torn upper film material and the torn lower film material are complete, and the upper film material and the lower film material can be completely torn from the plate. When there is an individual upper film material fixed sensor in the selected number of upper film material fixed sensors and / or there is an individual lower film material fixed sensor in the selected number of lower film material fixed sensors that cannot detect the film material, it is proved that there is local residual film material that cannot be stripped from the plate, and the plate on the plate output roller group 23 is unqualified and needs to be recycled / reworked, etc.

[0039] In the embodiment, the upper film material integrity detection mechanism 7 further comprises an upper distance adjusting mechanism arranged on the film tearing device 2 and two upper film material movable sensors arranged on the two adjusting ends of the upper distance adjusting mechanism.

The lower distance adjusting mechanism is used to adjust the distance between the two lower film material movable sensors. The lower distance adjusting mechanism is electrically connected with the width measurer 13.

[0040] In actual application, according to the width of the plate material, while the selected number of upper film material fixed sensors are used to detect the integrity of the upper film material of the stripped plate, the upper distance adjusting mechanism drives the two upper film material movable sensors to move close to or away from each other, so as to adjust the distance between the two upper film material movable sensors, and make the two upper film material movable sensors align with the two side edges of the upper film material respectively, so as to detect the two side edges of the upper film material. This avoids that the side edges of the upper film material cannot be accurately detected due to the detection blind area between the two adjacent upper film material fixed sensors, thereby improving the accuracy of the integrity detection of the upper film material.

[0041] Similarly, according to the width of the plate, a proper number of lower film material fixed inductors are selected to detect the integrity of the lower film material of the stripping plate, and at the same time, the lower spacing adjustment mechanism drives the two lower film material movable inductors to move close to or away from each other to adjust the spacing between the two lower film material movable inductors, so that the two lower film material movable inductors are aligned with the two side edges of the lower film material respectively to detect the two side edges of the lower film material, avoiding the situation that the side edges of the lower film material cannot be accurately detected due to the detection blind area between the two adjacent lower film material fixed inductors, thereby improving the accuracy of the integrity detection of the lower film material.

The upper film clamping device 5 is located on the discharge side of the upper film lifting mechanism 22, and the lower film clamping device is located on the discharge side of the lower film lifting mechanism 19. Specifically, the plate thickness detector 24 can be an ultrasonic thickness gauge.

[0044] In actual application, the plate feeding device 1 feeds the plate between the upper film-ripping mechanism 22 and the lower film-ripping mechanism 19. During the plate passing through the gap between the upper film-ripping mechanism 22 and the lower film-ripping mechanism 19, the upper film-ripping mechanism 22 separates the upper film on the plate, and the lower film-ripping mechanism 19 separates the lower film on the plate. With the movement of the plate, the end of the separated upper film is clamped by the film clamping end of the upper film clamping device 5 and pulled upward, and the end of the separated lower film is clamped by the film clamping end of the lower film clamping device 6 and pulled downward, so as to realize film tearing of the upper film and the lower film. When the plate feeding device 1 feeds the plate and passes through the plate thickness detector 24, the plate thickness detector 24 detects the thickness of the plate and feeds back the thickness detection result to the distance adjusting module 20. The distance adjusting module 20 drives the two adjusting seats 21 to move closer to or away from the lower film-ripping mechanism 19, so as to adjust the distance between the upper film-ripping mechanism 22 and the lower film-ripping mechanism 19, so as to automatically and accurately adjust the gap between the upper film-ripping mechanism 22 and the lower film-ripping mechanism 19 according to plates with different thicknesses, thereby realizing film tearing of plates with different thicknesses.

[0045] In the embodiment, the lower film-ripping mechanism 19 comprises a lower mounting seat 25 arranged on the base 17 and located between the two seat plates 18, a lower plate feeding roller set 26 rotatably arranged on the lower mounting seat 25, a rotation driving module 27 arranged on the seat plates 18 and used for driving the lower plate feeding roller set 26 and the plate output roller set 23 to rotate, a plurality of lower film rubbing wheel assemblies 28 arranged on the base 17 and linearly embedded in the middle of the lower plate feeding roller set 26, a lower film guide plate 29 arranged on the two seat plates 18 and located between the plate output roller set 23 and the lower plate feeding roller set 26, a lower guide roller 86 rotatably connected to the two seat plates 18 and located below the lower film guide plate 29, and a lower film pressing mechanism 30 arranged opposite to the lower guide roller 86, and the lower film clamping device 6 is located below the lower film guide plate 29. The upper film forming mechanism 22 comprises two connecting plates 31 respectively corresponding to the two adjusting seats 21, an upper mounting seat 32 mounted on the two connecting plates 31, an upper plate material input roller set 33 rotationally connected to the upper mounting seat 32 and arranged opposite to the lower plate material input roller set 26, a plurality of upper film rubbing wheel assemblies 34 mounted on the upper mounting seat 32 and linearly embedded in the middle of the upper plate material input roller set 33, an upper film guide plate 35 arranged between the plate output roller set 23 and the upper plate material input roller set 33 and arranged opposite to the lower film guide plate 29, an upper guide roller 85 arranged above the upper film guide plate 35, and an upper film pressing mechanism 36 arranged opposite to the upper guide roller 85. The upper film clamping device 5 is located above the upper film guide plate 35. The plurality of upper film rubbing wheel assemblies 34 are arranged one-to-one corresponding to the plurality of lower film rubbing wheel assemblies 28. The upper plate material input roller set 33 and the lower plate material input roller set 26 form a plate conveying gap therebetween. The upper film rubbing wheel assemblies 34 and the lower film rubbing wheel assemblies 28 form a film rubbing gap therebetween. The upper film guide plate 35 and the lower film guide plate 29 form a plate passing gap therebetween. The upper film rubbing wheel assemblies 34 and the lower film rubbing wheel assemblies 28 are both provided with film blowing air holes 37 for blowing air between the plate and the rubbed film. The upper film guide plate 35 is provided with an upper film separating tip 38 on the side close to the upper film rubbing wheel assemblies 34. The lower film guide plate 29 is provided with a lower film separating tip 39 on the side close to the lower film rubbing wheel assemblies 28. One end of the connecting plate 31 is rotationally connected to one end of the adjusting seat 21. The other end of the connecting plate 31 is detachably connected to the adjusting seat 21 through a locking structure 40. Specifically, the connecting plate 31 and the plate output mechanism 3 have a turnover space therebetween. Specifically, the upper film rubbing wheel assemblies 34 and the lower film rubbing wheel assemblies 28 can adopt the film rubbing wheel structure in the prior art, which will not be described here.

[0046] In practical application, the rotating drive module 27 drives the lower plate material input roller set 26 and the plate output roller set 23 to rotate, the plate material enters the plate feeding gap, the lower plate material input roller set 26 cooperates with the upper plate material input roller set 33 to drive the plate material to move, and when the moving plate material passes through the film rolling gap, the upper film rolling wheel assembly 34 cooperates with the lower film rolling wheel assembly 28 to roll the upper film material and the lower film material. Since the number of the upper film rolling wheel assembly 34 and the lower film rolling wheel assembly 28 is multiple, after multiple rolling of the upper film material and the lower film material, the local part of the upper film material and the local part of the lower film material will gradually peel off the plate, so that a gap is generated between the upper film material and the upper side of the plate to realize the film peeling of the upper film material, and a gap is generated between the lower film material and the lower side of the plate to realize the film peeling of the lower film material. At the same time, the film blowing air holes 37 on the upper film rolling wheel assembly 34 blow the positive pressure gas to the gap between the upper film material and the upper side of the plate, so that the upper film material stably peels off the plate, and the film blowing air holes 37 on the lower film rolling wheel assembly 28 blow the positive pressure gas to the gap between the lower film material and the lower side of the plate, so that the lower film material stably peels off the plate. With the movement of the plate and the gap between the film and the plate, the upper film separating tip 38 of the upper film guide plate 35 will be inserted into the gap between the upper film material and the upper side of the plate, and the lower film separating tip 39 of the lower film guide plate 29 will be inserted into the gap between the lower film material and the lower side of the plate. With the relative displacement of the plate and the film guide plate (the upper film guide plate 35 and the lower film guide plate 29), the plate will gradually enter the plate passing gap, the film guide plate will gradually peel off the plate, the peeled upper film material will enter the film clamping end of the upper film clamping device 5 located above the upper film guide plate 35 and be clamped by the upper film clamping device 5 to pull the film upward, the upper film material pulled upward moves upward around the upper guide roller 85, so that the upper film material completely peels off the plate, the peeled lower film material will enter the film clamping end of the lower film clamping device 6 located below the lower film guide plate 29 and be clamped by the lower film clamping device 6 to pull the film downward, the lower film material pulled downward moves downward around the lower guide roller 86, so that the lower film material completely peels off the plate, and the plate will move to the rotating plate output roller set 23 after passing through the plate passing gap, and the rotating plate output roller set 23 will output the plate. In addition, when the upper film peeling mechanism 22 and the lower film peeling mechanism 19 need to be disassembled and maintained, the locking structure 40 unlocks the connecting plate 31, so that the two connecting plates 31 can drive the upper mounting seat 32 to be flipped upward, so that the upper film peeling mechanism 22 and the lower film peeling mechanism 19 are relatively opened, providing an operating space for the operator. Through multiple rolling of the film (upper film and lower film), the success rate, stability and quality of film peeling (film stripping) are improved, the upper film peeling mechanism 22 can be relatively opened to the lower film peeling mechanism 19, and the upper film peeling mechanism 22 and the lower film peeling mechanism 19 do not need to be completely disassembled during disassembly and maintenance, which is convenient and efficient for disassembly and maintenance, and reduces the labor intensity of the operator.

[0047] In addition, the lower plate material input roller set 26 and the plate material output roller set 23 are driven to rotate synchronously by a rotating drive module 27, so that the number of driving sources is reduced, the structure is simplified, energy saving and environmental protection are achieved, and the cost is reduced.

[0048] Specifically, the upper film pressing mechanism 36 and the lower film pressing mechanism 30 comprise a film pressing driver 41, a pressing plate 42 arranged at the output end of the film pressing driver 41, and a film pressing roller 43 rotatably connected to the pressing plate 42. The film pressing driver 41 of the upper film pressing mechanism 36 is used to drive the pressing plate 42 and the film pressing roller 43 to move close to or away from the upper guide roller 85, and the film pressing driver 41 of the lower film pressing mechanism 30 is used to drive the pressing plate 42 and the film pressing roller 43 to move close to or away from the lower guide roller 86. Specifically, the film pressing driver 41 can be a gas cylinder, which is arranged obliquely.

[0049] In actual application, when the upper film clamping device 5 clamps the upper film material and pulls the upper film material forward to tear the film, the film pressing driver 41 of the upper film pressing device drives the pressing plate 42 and the film pressing roller 43 to move close to the upper guide roller 85, so that the film pressing roller 43 presses the upper film material to the upper guide roller 85. As the upper film material moves upward, the film pressing roller 43 and the upper guide roller 85 rotate on both sides of the upper film material, so as to ensure the stability and flatness of the film tearing and the accuracy of the integrity detection of the upper film material by the upper film material integrity detection mechanism 7, and avoid affecting the accuracy of the film material integrity detection due to the floating or swinging of the upper film material. Similarly, the film pressing driver 41 of the lower film pressing mechanism 30 drives the pressing plate 42 and the film pressing roller 43 to move close to the lower guide roller 86, so that the film pressing roller 43 presses the lower film material to the lower guide roller 86. As the lower film material moves downward, the film pressing roller 43 and the lower guide roller 86 rotate on both sides of the lower film material, so as to ensure the stability and flatness of the film tearing and the accuracy of the integrity detection of the lower film material by the lower film material integrity detection mechanism 8, and avoid affecting the accuracy of the film material integrity detection due to the floating or swinging of the lower film material.

[0050] In the embodiment, the locking structure 40 comprises a locking seat 44, an operating handle 45, an elastic member, and a clamping rod 46. The locking seat 44 is arranged on the connecting plate 31, the clamping rod 46 is arranged on the adjusting seat 21, the middle part of the operating handle 45 is rotatably connected to the locking seat 44, the lower part of the operating handle 45 is provided with a clamping hook 47 for clamping the clamping rod 46, and the elastic member is connected to the middle and upper part of the operating handle 45 and the locking seat 44. The elastic force of the elastic member acts on the clamping rod 46 through the clamping hook 47 of the operating handle 45. Specifically, the elastic member is a spring.

[0051] In actual application, when the locking structure 40 locks the connecting plate 31 and the adjusting seat 21 together, the elastic member is in the stretched state and applies a pushing force to the middle part of the operating handle 45, so that the clamping hook 47 of the operating handle 45 can be firmly clamped with the clamping rod 46. When it is needed to unlock the connecting plate 31 and the adjusting seat 21, an acting force overcoming the elastic force of the elastic member is applied to the upper part of the operating handle 45, so that the operating handle 45 rotates, thereby making the clamping hook 47 of the operating handle 45 disengage from the clamping rod 46, and making the connecting plate 31 be able to rotate relative to the adjusting seat 21, thereby making the upper film-feeding mechanism 22 open relative to the lower film-feeding mechanism 19. The locking structure 40 has simple structure, easy and convenient operation, and low cost.

[0052] Specifically, the connecting plate 31 is provided with the distance adjusting units 48, and the two ends of the upper film-feeding plate 35 are respectively arranged on the adjusting ends of the two distance adjusting units 48. The distance adjusting units 48 are used to adjust the distance between the upper film-feeding plate 35 and the lower film-feeding plate 29. In actual application, the thicknesses of the plate members in different plate materials are different. When the thickness of the plate member changes, the distance adjusting units 48 drive the upper film-feeding plate 35 to move close to or away from the lower film-feeding plate 29, so as to adjust the distance between the upper film-feeding plate 35 and the lower film-feeding plate 29, thereby adjusting the size of the over-plate gap, so as to meet the plate members with different thicknesses passing through the over-plate gap. The structure design makes the machine not only be able to meet the production of plate materials with different thicknesses, but also be able to meet the production of plate materials with the same total thickness but different plate member thicknesses.

[0053] Specifically, the connecting plate 31 is provided with the lifting driver 49, and the upper guide roller 85 is rotationally connected to the lifting end of the lifting driver 49. The lifting driver 49 is used to drive the upper guide roller 85 to lift. Specifically, the lifting driver 49 can adopt a pneumatic cylinder. In actual application, according to the height adjustment of the upper film-feeding plate 35 by the distance adjusting units 48, the lifting driver 49 drives the upper guide roller 85 to lift, so as to adjust the height position of the upper guide roller 85, thereby making the upper guide roller 85 be able to guide the upwardly pulled upper film material at a suitable position.

[0054] In the embodiment, the upper film-feeding mechanism 22 further comprises the upper static electricity removing module 50 and the upper air blowing pipe 51 arranged on the side of the upper mounting seat 32 close to the upper guide roller 85. The upper air blowing pipe 51 is axially provided with a plurality of air blowing holes 72. The air blowing holes 72 of the upper air blowing pipe 51 are obliquely downwardly directed to the top surface of the upper film-feeding plate 35. The lower film-feeding mechanism 19 further comprises the lower static electricity removing module 53 and the lower air blowing pipe 54 arranged on the side of the lower mounting seat 25 close to the lower guide roller 86. The lower air blowing pipe 54 is axially provided with a plurality of air blowing holes 72. The air blowing holes 72 of the lower air blowing pipe 54 are obliquely upwardly directed to the bottom surface of the lower film-feeding plate 29. Specifically, the upper static electricity removing module 50 and the lower static electricity removing module 53 can both adopt static electricity removing rods.

[0055] In actual application, when the upper film guide plate 35 is inserted between the upper film and the plate, the air blowing holes 72 of the upper air blowing pipe 51 blow air to the upper film on the upper film guide plate 35 obliquely downward, so that the upper film is flat, the end of the peeled upper film is prevented from being bent, and the film clamping end of the upper film clamping device 5 clamps the end of the upper film accurately; when the upper film clamping device 5 pulls the upper film to move upward, the upper electrostatic removal module 50 removes static electricity from the upper film. When the lower film guide plate 29 is inserted between the lower film and the plate, the air blowing holes 72 of the lower air blowing pipe 54 blow air to the lower film on the lower film guide plate 29 obliquely upward, so that the lower film is flat, the end of the peeled lower film is prevented from being bent, and the film clamping end of the lower film clamping device 6 clamps the end of the lower film accurately; when the lower film clamping device 6 pulls the lower film to move downward, the lower electrostatic removal module 53 removes static electricity from the lower film.

[0056] Specifically, a plurality of support rollers 55 are rotationally connected between the two seat plates 18, the axes of the plurality of support rollers 55 are in the same horizontal plane, the plurality of support rollers 55 are located between the plate output roller group 23 and the lower film guide plate 29, and the plurality of support rollers 55 are located at the turnover space. During the movement of the plate through the plate gap to the plate output roller group 23, the plurality of support rollers 55 support the plate, avoid the large spacing between the output end of the plate gap and the plate output roller group 23 due to the turnover space between the connecting plate 31 and the plate output roller group 23, prevent the local bending deformation of the plate output from the plate gap, and facilitate to ensure the quality of the plate.

[0057] Specifically, the film tearing device 2 further comprises a press roller 56 arranged above the plate output roller group 23 and a lifting driving module 57 arranged on the seat plate 18, the press roller 56 is rotationally connected to the lifting end of the lifting driving module 57, and the lifting driving module 57 is used to drive the press roller 56 to approach or move away from the plate output roller group 23; specifically, the lifting driving module 57 can adopt a pneumatic cylinder, a linear motor or an electric screw rod module. In actual application, according to the different thicknesses of the plates, the lifting driving module 57 drives the press roller 56 to lift, so as to adjust the gap size between the press roller 56 and the plate output roller group 23, so as to meet the conveying of plates with different thicknesses. In addition, the plate is pressed on the plate output roller group 23 by the press roller 56, so as to improve the stability of the plate conveying.

[0058] In the embodiment, the upper film clamping device 5 and the lower film clamping device 6 each include a horizontal movement driving mechanism 58, a horizontal film clamping mechanism 59 arranged at the moving end of the horizontal movement driving mechanism 58, a vertical movement driving mechanism 60 arranged at one side of the horizontal movement driving mechanism 58, a vertical film clamping mechanism 61 arranged at the moving end of the vertical movement driving mechanism 60, a lifting driving mechanism 62 arranged at the other side of the horizontal movement driving mechanism 58, and a stacking table 63 arranged at the lifting end of the lifting driving mechanism 62. The vertical film clamping mechanism 61 is movably arranged between the horizontal film clamping mechanism 59 and the lifting driving mechanism 62, and the stacking table 63 is vertically movable above or below the horizontal film clamping mechanism 59. The horizontal movement driving mechanism 58 is configured to drive the horizontal film clamping mechanism 59 to move close to or away from the vertical film clamping mechanism 61, and the vertical movement driving mechanism 60 is configured to drive the vertical film clamping mechanism 61 to move vertically. The vertical film clamping mechanism 61 of the upper film clamping device 5 is vertically arranged above the upper film guide plate 35, and the vertical film clamping mechanism 61 of the lower film clamping device 6 is vertically arranged below the lower film guide plate 29. The horizontal film clamping mechanism 59 of the upper film clamping device 5 and the horizontal film clamping mechanism 59 of the lower film clamping device 6 are respectively arranged at the upper and lower sides of the plate material feeding device 1.

[0059] In practical applications, the upper film clamping device 5 and the lower film clamping device 6 have two working states; the working principle of the lower film clamping device 6 is the same as that of the upper film clamping device 5, and the upper film clamping device 5 is taken as an example for description. The first working state: at the beginning, the stacking table 63 is lifted and arranged below the horizontal film clamping mechanism 59, the vertical film clamping mechanism 61 is in the lowest position, and the film clamping end of the vertical film clamping mechanism 61 is in an open clamping state. After one end of the upper film material enters the film clamping end of the vertical film clamping mechanism 61, the film clamping end of the vertical film clamping mechanism 61 clamps one end of the upper film material, and then the vertical movement driving mechanism 60 drives the vertical film clamping mechanism 61 and the upper film material clamped thereby to move upward. The upper film material is bent upward around the bottom of the upper guide roller 85 and moves upward. When the vertical film clamping mechanism 61 moves upward to a position higher than the top surface of the upper guide roller 85, the upper film material is pressed toward the upper guide roller 85 by the upper film pressing mechanism 36. The film pressing roller 43 of the upper film pressing mechanism 36 and the upper guide roller 85 are in rolling contact with the two sides of the upper film material, respectively, to guide the upward movement of the upper film material and avoid the upper film material from floating or being bent during the upward movement, so as to ensure that the upper film material can move upward smoothly and flatly. When the vertical film clamping mechanism 61 rises to a predetermined height and the upper film material is completely separated from the plate, the horizontal movement driving mechanism 58 drives the horizontal film clamping mechanism 59 to move close to the film clamping end of the vertical film clamping mechanism 61 until the film clamping end of the horizontal film clamping mechanism 59 clamps the upper film material of the vertical film clamping mechanism 61, and then the film clamping end of the vertical film clamping mechanism 61 releases the upper film material. Then the horizontal movement driving mechanism 58 drives the horizontal film clamping mechanism 59 and the upper film material clamped thereby to move away from the vertical film clamping mechanism 61 until the upper film material is pulled onto the stacking table 63. The stacking table 63 supports the film material, and the horizontal film clamping mechanism 59 releases the upper film material so that the upper film material is stably stacked on the stacking table 63 or the film material on the stacking table 63. When the upper film material on the vertical film clamping mechanism 61 is clamped by the horizontal film clamping mechanism 59, the film pressing roller 43 of the upper film pressing mechanism 36 moves away from the upper guide roller 85 and returns to the original position. The vertical movement driving mechanism 60 drives the vertical film clamping mechanism 61 to move downward and return to the original position. The above film pulling operation is repeated to stack the upper film material on the stacking table 63. When the stacking table 63 is lowered by one piece of the upper film material for each piece of the upper film material stacked on the stacking table 63, the upper film material can be stably stacked on the stacking table 63. When the number of the upper film materials stacked on the stacking table 63 reaches a predetermined number, a stack of the film materials stacked in an orderly manner can be taken from the stacking table 63, so that the upper film material can be collected and recycled.

[0060] The second working state: initially, the stacking table 63 is located above the transverse film clamping mechanism 59, the storage frame 84 is arranged below the transverse film clamping mechanism 59, the stacking table 63 is located above the storage frame 84, the stacking table 63 is provided with an avoiding groove 87, the avoiding groove 87 can be passed through by the transverse film clamping mechanism 59, the longitudinal film clamping mechanism 61 is located at the lowest position, and the film clamping end of the longitudinal film clamping mechanism 61 is in an open clamping state. After one end of the upper film material enters the film clamping end of the longitudinal film clamping mechanism 61, the film clamping end of the longitudinal film clamping mechanism 61 clamps one end of the upper film material. Then, the longitudinal displacement driving mechanism 60 drives the longitudinal film clamping mechanism 61 and the upper film material clamped thereby to move upward. The upper film material is bent upward around the bottom of the upper guide roller 85. When the longitudinal film clamping mechanism 61 moves upward to be higher than the top surface of the upper guide roller 85, the upper film pressing mechanism 36 drives the film pressing roller 43 to move close to the upper guide roller 85, so that the film pressing roller 43 of the upper film pressing mechanism 36 and the upper guide roller 85 are in rolling contact with the two sides of the upper film material respectively, to guide the upward movement of the upper film material, avoid the upper film material from floating or being bent during the upward movement, and ensure that the upper film material can move upward smoothly and flatly. When the longitudinal film clamping mechanism 61 rises to a preset height and the upper film material is completely separated from the plate, the transverse displacement driving mechanism 58 drives the transverse film clamping mechanism 59 to move close to the film clamping end of the longitudinal film clamping mechanism 61. After the film clamping end of the transverse film clamping mechanism 59 clamps the upper film material of the longitudinal film clamping mechanism 61, the film clamping end of the longitudinal film clamping mechanism 61 releases the upper film material. Then, the transverse displacement driving mechanism 58 drives the transverse film clamping mechanism 59 and the upper film material clamped thereby to move away from the longitudinal film clamping mechanism 61. When the upper film material is pulled to be below the stacking table 63, the transverse film clamping mechanism 59 releases the upper film material, and the lifting driving mechanism 62 quickly drives the stacking table 63 to move downward close to the storage frame 84, so that the avoiding groove 87 of the stacking table 63 passes through the transverse film clamping mechanism 59 and quickly presses the upper film material into the storage frame 84, so that the upper film materials stacked in the storage frame 84 are closely attached to each other, the film materials are not loose, and the upper film materials can be stably stacked in the storage frame 84. After the stacking table 63 presses one piece of upper film material into the storage frame 84, the stacking table 63 is raised to reset to be above the transverse film clamping mechanism 59, so as to press the next piece of film material. When the storage frame 84 is full of film materials, a group of film materials can be taken away.

[0061] The upper film clamping device 5 and the lower film clamping device 6 of the structure can realize film material pulling and stable and neat stacking and collection of the film material. The stacked film materials are not loose, and the film materials are convenient for recycling.

[0062] In the embodiment, the transverse film clamping mechanism 59 comprises a moving seat 64 arranged at the moving end of the transverse driving mechanism 58 and a transverse film clamping module 65 arranged at the moving seat 64. The transverse film clamping module 65 comprises a transverse film clamping driver 66 arranged at the moving seat 64, two transverse film clamping plates 67 respectively arranged at the two output ends of the transverse film clamping driver 66 and oppositely arranged, and a plurality of film clamping blocks 68 protruding from the front surface of the transverse film clamping plates 67. The plurality of film clamping blocks 68 are arranged at intervals. The transverse film clamping driver 66 is used to drive the two transverse film clamping plates 67 to move close to or away from each other. The film clamping end of the longitudinal film clamping mechanism 61 is provided with a plurality of avoiding openings 69. The plurality of avoiding openings 69 are respectively arranged in one-to-one correspondence with the plurality of film clamping blocks 68. The film clamping blocks 68 can extend into the avoiding openings 69. Specifically, the transverse film clamping driver 66 can adopt a finger air cylinder.

[0063] In actual application, the transverse driving mechanism 58 drives the moving seat 64 and the transverse film clamping module 65 to move close to or away from the longitudinal film clamping mechanism 61. Specifically, in the process that the longitudinal film clamping mechanism 61 pulls the upper film material upward to the preset height position and the upper film material is completely separated from the plate, the transverse film clamping driver 66 drives the two transverse film clamping plates 67 to move away from each other, so that the plurality of film clamping blocks 68 on the two transverse film clamping plates 67 are opened to each other. The transverse driving mechanism 58 drives the moving seat 64 and the transverse film clamping module 65 in the opened state to move to the film clamping position, so that the film clamping blocks 68 on the transverse film clamping plates 67 move into the avoiding openings 69. The upper film material clamped by the longitudinal film clamping mechanism 61 is located between the film clamping blocks 68 of the two transverse film clamping plates 67. Then, the transverse film clamping driver 66 drives the two transverse film clamping plates 67 to move close to each other, so that the plurality of film clamping blocks 68 on the two transverse film clamping plates 67 are closed to each other and clamp the upper film material. At this time, the film clamping end of the longitudinal film clamping mechanism 61 releases the upper film material. Then, the transverse driving mechanism 58 drives the moving seat 64, the transverse film clamping module 65 and the upper film material to move away from the longitudinal film clamping mechanism 61. When the upper film material moves to the preset position of the stacking table 63, the stacking table 63 supports the film material. The transverse film clamping driver 66 drives the two transverse film clamping plates 67 to move away from each other, so that the plurality of film clamping blocks 68 on the two transverse film clamping plates 67 are opened to release the upper film material. The upper film material is stably stacked on the stacking table 63 or the stacking table 63 presses the upper film material into the film storage frame 84.

[0064] In the embodiment, the transverse film clamping plates 67 are provided with air passages 70, the film clamping blocks 68 are internally provided with air cavities 71 in communication with the air passages 70, and the film clamping surfaces of the film clamping blocks 68 are provided with air blowing holes 72 in communication with the air cavities 71; the air passages 70 are communicated with air blowing mechanisms, and the air blowing mechanisms introduce positive pressure gas into the air passages 70. When the film material is adhered to the film clamping blocks 68 or moves with the film clamping blocks 68 to cause displacement of the film material due to static electricity or negative pressure between the film material and the film clamping blocks 68 after the opening of the film clamping blocks 68 on the two transverse film clamping plates 67, the film material is not only affected in neat stacking, but also affects the normal operation of the transverse film clamping mechanism 59. In order to overcome the above problems, when the film clamping blocks 68 on the two transverse film clamping plates 67 are opened, the air blowing mechanisms introduce positive pressure gas into the air passages 70, the positive pressure gas flows into the air cavities 71 along the air passages 70 and forms a positive pressure air flow, and the positive pressure air flow is blown out of the air blowing holes 72. The positive pressure air flow blows the film material away from the film clamping blocks 68 to realize stable separation of the film material from the film clamping blocks 68, thereby improving the stability and neatness of the film material in stacking on the stacking table 63 or being pressed into the film storage frame 84 by the stacking table 63.

[0065] In the embodiment, the longitudinal film clamping mechanism 61 further comprises film pushing arms 73 movably arranged on the sides of the two transverse film clamping plates 67 and a film pushing driver 74 arranged on the moving seat 64 and used for driving the film pushing arms 73 to move back and forth. Specifically, the film pushing driver 74 can be a pneumatic cylinder. When the film clamping blocks 68 on the two transverse film clamping plates 67 are opened, the film pushing driver 74 drives the film pushing arms 73 to translate towards the longitudinal film clamping mechanism 61, and the translating film pushing arms 73 push the film material away from the film clamping blocks 68 to realize stable separation of the film material from the film clamping blocks 68. Of course, according to different use requirements of users, the positive pressure air flow blowing the film material away from the film clamping blocks 68 and the film pushing arms 73 pushing the film material away from the film clamping blocks 68 can be used alternatively or simultaneously.

[0066] Specifically, the number of the film pushing arms 73 is two, and the two film pushing arms 73 are respectively located on the two sides of the transverse film clamping plates 67. The two film pushing arms 73 push the film material away from the film clamping blocks 68, thereby improving the stability of film pushing and making the film material bear force uniformly and not easily bent.

[0067] Specifically, a connecting rod 75 is connected between the two film pushing arms 73, so that the connecting rod 75 and the two film pushing arms 73 form a U-shaped structure, and a driving end of the film pushing driver 74 is connected with the connecting rod 75. With this structure, the film pushing driver 74 can drive the connecting rod 75 and the two film pushing arms 73 to translate synchronously.

[0068] Specifically, the push film arm 73 is provided with a guide groove 76, and the moving seat 64 is provided with a guide rod 77 penetrating through the guide groove 76 and in sliding fit with the guide groove 76; in the reciprocating movement of the push film arm 73, the guide rod 77 and the guide groove 76 are in sliding fit, thereby improving the stability of the movement of the push film arm 73.

[0069] Specifically, the film clamping block 68 is L-shaped, and the guide rod 77 is located between the two transverse film clamping plates 67. This structure design makes the structure between the film clamping block 68, the transverse film clamping plate 67 and the guide rod 77 compact, and requires small occupied space.

[0070] Specifically, the number of the transverse film clamping modules 65 is multiple, the multiple transverse film clamping modules 65 are arranged at intervals, the stacking table 63 is provided with multiple avoiding grooves 87, the multiple transverse film clamping modules 65 are arranged one by one corresponding to the multiple avoiding grooves 87, and the avoiding grooves 87 provide avoiding space for the transverse film clamping modules 65. This structure design is conducive to film stretching of film material with relatively large width, and the transverse film clamping modules 65 will not collide or interfere with the stacking table 63.

[0071] Specifically, the longitudinal film clamping mechanism 61 includes a lifting seat 78 arranged at the moving end of the longitudinal moving driving mechanism 60 and a longitudinal film clamping module 79 arranged at the lifting seat 78. The longitudinal film clamping module 79 includes a longitudinal film clamping driver 80 arranged at the lifting seat 78, a fixed plate 81 arranged at the lifting seat 78, multiple L-shaped clamping blocks 82 arranged at the bottom of the fixed plate 81 at intervals, a movable clamping plate 83 arranged at the driving end of the longitudinal film clamping driver 80 and located at one side of the fixed plate 81, and multiple movable clamping blocks 88 arranged at the bottom of the movable clamping plate 83 at intervals. The multiple movable clamping blocks 88 are arranged one by one corresponding to the multiple L-shaped clamping blocks 82, the movable clamping blocks 88 are located above the horizontal parts of the L-shaped clamping blocks 82, and the longitudinal film clamping driver 80 is used to drive the movable clamping plate 83 and the movable clamping blocks 88 to move close to or away from the horizontal parts of the L-shaped clamping blocks 82. The avoiding opening 69 is located between the two adjacent L-shaped clamping blocks 82. Specifically, the longitudinal film clamping driver 80 can be a vertical downward air cylinder.

[0072] In actual application, the longitudinal film clamping driver 80 drives the movable clamping plate 83 and the multiple movable clamping blocks 88 to move upward, so that the multiple movable clamping blocks 88 and the multiple L-shaped clamping blocks 82 are in an open state. At this time, one end of the film material moves into the space between the movable clamping blocks 88 and the L-shaped clamping blocks 82. Then, the longitudinal film clamping driver 80 drives the movable clamping plate 83 and the multiple movable clamping blocks 88 to move downward, so that the multiple movable clamping blocks 88 and the multiple L-shaped clamping blocks 82 are closed and clamp the film material. Then, the longitudinal moving driving mechanism 60 drives the lifting seat 78, the longitudinal film clamping module 79 and the film material above to move upward.

[0073] Specifically, the number of the longitudinal film clamping modules 79 is multiple, and the multiple longitudinal film clamping modules 79 are arranged one by one corresponding to the multiple transverse film clamping modules 65; this structural design can clamp and pull the film material with a wider width.

[0074] In another embodiment, when the stacking table 63 is located below the transverse film clamping mechanism 59, the upper film clamping device 5 and the lower film clamping device 6 further comprise a lifting driving unit arranged in parallel with the lifting driving mechanism 62 and a pressing table arranged at the lifting end of the lifting driving unit, the pressing table is provided with a through slot capable of allowing the transverse film clamping mechanism 59 to pass through, and the pressing table is arranged in an up-down opposite manner with the stacking table 63; initially, the pressing table is located above the transverse film clamping mechanism 59.

[0075] In actual application, when the transverse film clamping mechanism 59 clamps the film material and moves to the upper side of the stacking table 63, the transverse film clamping mechanism 59 releases the film material at the same time, and the lifting driving module 57 drives the pressing table to move downward rapidly, so that the pressing table presses the film material on the stacking table 63 rapidly, so that the film materials stacked on the stacking table 63 are close to each other, avoiding the looseness between the stacked film materials, so that the film materials can be stably stacked on the stacking table 63; after the pressing table presses the film material on the stacking table 63, the lifting driving unit drives the pressing table to rise and reset, so that the pressing table is located above the transverse film clamping mechanism 59; every time the stacking table 63 increases one piece of film material, the lifting driving mechanism 62 can drive the stacking table 63 to move downward by one piece of film material, so that the stacking table 63 can stably stack the film materials.

[0076] All the technical features in the embodiment can be freely combined according to actual needs.

[0077] The above embodiments are the preferred implementation of the present application, in addition to this, the present application can be realized in other ways, without departing from the technical solution concept of the present application, any obvious replacement is within the protection scope of the present application.
